Embodiment Construction

[0050] The flow-based quality of service implementation system for mobile IP services of the present invention includes a mobile IP user terminal AT, a wireless access network node RAN, an access server PDSN / foreign agent node (FA, Foreign Agent) and a home agent HA node. The core of the method of the present invention is to combine the characteristics of mobile IP services, to increase the stream quality of service information interface between the access server / foreign agent and the home agent HA, so that the access server / foreign agent establishes with mobile IP user terminals and wireless network nodes After the upstream and downstream QoS mapping relationship is maintained, the flow QoS information (including upstream and downstream flow filters or flow QoS parameters) containing the flow mapping relationship can be transmitted to the HA node through the information interface. Wherein, the information interface can be implemented through the extension field in the registra...

Abstract

The invention discloses a method for realizing a mobile IP service of flow based QoS (quality of service), involving a mobile IP user terminal AT, a RAN node, an access server or a foreign agent node and a Ha node. The method comprises the following steps that: (a) a flow based QoS information interface is added between the access server or the foreign agent and the HA node; (b) after QoS mapping relationship between up-link and down-link is established and maintained between the access server or the foreign agent and the AT and RAN nodes, the flow based OoS information containing the flow QoS mapping relationship is transferred to the HA node via the OoS information interface. The invention combines the characteristics of MIP service and transfers the flow based QoS information to the HA node by adding a message interface between the access server / foreign agent node and the HA node, and thus the flow based OoS insurance scope of MIP service and the insurance system of the flow based QoS at the core network side are improved.

Description

technical field [0001] The present invention relates to a quality of service (QoS, Quality of Service) guarantee technology in the field of mobile communication, in particular to a method and system for realizing flow-based quality of service of a mobile IP (MIP, Mobile Internet Protocol) service. Background technique [0002] Code-Division Multiple Access (CDMA, Code-Division Multiple Access) 2000, in addition to the characteristics of general CDMA systems such as large capacity and strong anti-interference ability, is also very prominent in supporting high-speed data services. In order to enable wireless users to have rich and high-quality data services, High Rate Packet Data (HRPD, High Rate Packet Data) is introduced into flow-based QoS guarantee on the basis of multi-service connections. Under this mechanism, the user's packet data is mapped into a flow, which is carried on different radio network-packet data serving node (RN-PDSN, Radio Network-Packet Data ServingNode)...
